preparation example Construction
[0029] combine figure 1 , Figure 5 and Figure 6 , the present invention has the double Y-shaped steel fiber of self-anchoring function, and its preparation method is as follows: adopt thickness to be D 3 The steel plate is formed by punching, stretching and cutting, that is, the steel fiber straight section and the anchor section located at both ends of the straight section form an integrated double Y-shaped steel fiber. The anchor section is the first anchor section 1 and the second anchor section 2. , the third anchoring section 3, and the fourth anchoring section 4, wherein the first anchoring section 1 and the second anchoring section 2, the third anchoring section 3 and the fourth anchoring section 4 respectively form a Y-shaped section, and the first anchoring section 1 and the fourth anchoring section 4 form a Y-shaped section respectively. The anchor opening angle between the second anchor segment 2, the third anchor segment 3 and the fourth anchor segment 4 is 2θ,...
Embodiment 1
[0049] 1. Take a steel plate with a width of 1.2 meters, a length greater than 1 meter, and a thickness of D3 = 0.5mm;
[0050] 2. The value of L1 is 10mm, the value of L2 is 2mm, the value of 2θ is 60°, the value of D2 is 0.25mm, and the width D1 of the straight line section of steel fiber is 0.5mm;
[0051] 3. Calculated: L0 is 18mm, L3 is 1.7mm, and L4 is 13.5mm. According to the above data, the structural size of the double Y-shaped steel fiber can be drawn, see figure 1 .
[0052] The processing process is carried out according to the steps of the above method, and the processing parameters are: punching length 18mm, incision interval 10mm, y-direction moving distance (D2) 0.25mm, x-direction horizontal moving distance (L1+2L2) 14mm.
Embodiment 2
[0054] 1. Take a width of 1 meter, a length greater than 1 meter, and a thickness of D 3 = 1mm steel plate;
[0055] 2. L 1 Value 20mm, L 2 The value is 4mm, the value of 2θ is 90°, D 2 The value is 0.4mm, the width of steel fiber straight section D 1 0.8mm;
[0056] 3. Calculated: L 0 36mm, L 3 2.83mm, L 4 is 25.7mm, according to the above data, the structural size of the double Y-shaped steel fiber can be drawn, see figure 1 .
[0057] The processing process is carried out according to the above-mentioned method steps, and each processing parameter is: punching length 36mm, slit interval 20mm, y direction moving distance (D 2 )0.4mm, horizontal movement distance in x direction (L 1 +2L 2 )28mm.
